Product details
Overview
TLV62568ADRLR from Texas Instruments is a synchronous step-down DC-DC converter delivering up to 2 A output current with forced PWM operation, 1.5-MHz switching frequency, and 95% peak efficiency at 5-V input. It operates across 2.5 V to 5.5 V input, regulates output from 0.6 V to VIN, and integrates low-RDS(on) power switches (100 mΩ/60 mΩ) for high-efficiency POL conversion in space-constrained applications like IP cameras and SSDs.
For engineers reviewing the TLV62568ADRLR datasheet, TLV62568ADRLR pinout, TLV62568ADRLR application, or TLV62568ADRLR equivalent, this page delivers verified electrical specs, SOT563 package details, functional pin definitions, real-world efficiency curves, and validated alternative parts - all aligned with TI's production-grade SLVSE95B revision March 2020 documentation.
Technical Context
The TLV62568ADRLR uses peak-current-mode control with adaptive off-time modulation to maintain stable 1.5-MHz switching across input (2.5–5.5 V), output (0.6–VIN), and load (0–2 A) variations. Its internal soft-start circuit limits inrush current during enable, and it supports 100% duty-cycle operation for ultra-low dropout under light loads.
It features integrated overcurrent protection via high-side FET current sensing, thermal shutdown at 150°C, UVLO with 2.45-V threshold and 100-mV hysteresis, and ±1% feedback voltage accuracy (0.6 V ±12 mV). The device draws <2 µA shutdown current and maintains regulation down to 0.6 V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 2 A maximum continuous - supports compact 1.8-V/2-A POL rails without external current-sense resistors |
| Input voltage range | 2.5 V to 5.5 V - compatible with single-cell Li-ion, USB, and 3.3-V/5-V system rails |
| Switching frequency | 1.5 MHz typical - enables use of small 1-µH inductors and reduces EMI filtering burden |
| Peak efficiency | 95% at 5-V input / 1.8-V/2-A output - minimizes thermal load in sealed enclosures |
| Feedback voltage | 0.6 V ±12 mV - sets precise output via external resistor divider; enables 0.6–VIN adjustable range |
| RDS(on) | 100 mΩ (high-side) / 60 mΩ (low-side) - reduces conduction loss and improves light-load efficiency |
| Shutdown current | <2 µA - preserves battery life in always-on IoT endpoints and standby modes |
Pinout & Package
SOT563-6 package (1.60 mm × 1.60 mm, 0.6-mm height), thermally enhanced with exposed pad; pin-compatible with TLV62568/62569 family and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (Pin 1) | Feedback input | Connects to resistor divider midpoint; regulates output by comparing to 0.6-V internal reference |
| GND (Pin 2) | Power ground | Main return path for input/output currents; must be low-impedance connection to thermal pad |
| VIN (Pin 3) | Input power supply | Accepts 2.5–5.5 V; requires local 4.7-µF ceramic capacitor for high-frequency decoupling |
| SW (Pin 4) | Switch node | Drives external 1-µH inductor; connects internally to both FETs; high dv/dt node requiring tight layout |
| EN (Pin 5) | Enable logic input | Active-high (VIH ≥1.2 V); disables converter and reduces quiescent current to <2 µA when pulled low |
| NC (Pin 6) | No connection | Not bonded; may be left floating or connected to GND/output for improved thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Forced PWM mode | Eliminates frequency variation and output ripple spikes during light-load conditions |
| 100% duty-cycle operation | Enables dropout as low as IOUT × (RDS(on) + LDCR) - critical for battery-powered systems near end-of-life |
| Internal soft-start | 0.9-ms ramp time prevents inrush current damage to input capacitors and upstream regulators |
| Overcurrent protection | Peak-current limiting triggers at 2 A (typical), protecting against short-circuit and overload faults |
| Thermal shutdown | Auto-recovery at 130°C after trip at 150°C - ensures safe operation without manual reset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV62569ADRLR | 2-A rated with identical pinout and specs; differs only in internal current limit (3 A vs 2 A for TLV62568ADRLR) | Preferred where future-proofing for higher transient loads or margin-based design is required | Select TLV62569ADRLR if board layout must support upgrade path to 3-A peak current without redesign |
| TPS6286518RTER | 1.8-V fixed-output, 4-A capable, 2.5–5.5-V input, 2.2-MHz switching; smaller 1.2-mm × 0.8-mm DSBGA package | Better suited for ultra-dense portable designs needing higher current and lower profile than SOT563 | Choose TPS6286518RTER when >2-A capability, sub-1-mm height, or fixed 1.8-V output simplifies BOM |
Compared with TLV62568ADRLR, TLV62569ADRLR offers higher current headroom in identical packaging, while TPS6286518RTER trades pin compatibility for greater density and output current - making TLV62568ADRLR optimal for cost-sensitive, space-constrained 2-A POL applications where layout reuse matters.

FAQ
What is the maximum output current rating of the TLV62568ADRLR?
The TLV62568ADRLR is rated for up to 2 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, 2.5–5.5 V input). Its internal current limit is typically 2 A, as confirmed in Section 6.5 of the SLVSE95B datasheet. This rating assumes proper PCB thermal design using the SOT563 package's exposed pad and adequate copper area.
Does the TLV62568ADRLR support power good (PG) functionality?
No, the TLV62568ADRLR does not include a power good output. Only the TLV62568APDRL and TLV62569APDRL variants feature the PG pin. The TLV62568ADRLR has an NC (no-connect) terminal at Pin 6, which may be left floating or tied to GND/output for thermal enhancement but provides no monitoring function.
What is the recommended inductor value for a 1.8-V/2-A TLV62568ADRLR design?
The recommended inductor value for a 1.8-V/2-A TLV62568ADRLR application is 1.0 µH, as specified in the typical application schematic (Figure 6) and Table 3 of the SLVSE95B datasheet. Coilcraft XAL4020-102ME is a validated part; saturation current should exceed 2.6 A (20% above 2 A) to ensure stability under peak load.
Can the TLV62568ADRLR operate with a 0.6-V output voltage?
Yes, the TLV62568ADRLR supports output voltages as low as 0.6 V, set via an external resistor divider on the FB pin. Its feedback reference is precisely 0.6 V ±12 mV, enabling accurate low-voltage regulation for modern SoCs and FPGAs. Output accuracy remains within ±1% over temperature and line/load conditions.
Is the TLV62568ADRLR pin-to-pin compatible with other devices in the TLV6256x family?
Yes, the TLV62568ADRLR is pin-to-pin compatible with TLV62568APDRL, TLV62569ADRLR, and TLV62569APDRL in the SOT563-6 package. All share identical pin configuration (FB, GND, VIN, SW, EN, NC/PG), allowing direct substitution in existing layouts - though PG functionality and current ratings differ between variants.
